Objective: To study the clinical effect of double-beam anatomical reconstruction of medial patellofemoral ligament under arthroscopy.
Methods: Double-beam anatomical reconstruction of medial patellofemoral ligament was performed under arthroscopy in patients admitted to our hospital for treatment of recurrent patellar dislocation. Carry out preoperative and postoperative evaluations, and conduct preoperative and postoperative comparative studies to clarify the clinical effect of the procedure.
Expected results: Arthroscopic double-beam anatomical reconstruction of the medial patellofemoral ligament can effectively restore the stability of the patella and the motor function of the knee joint.
Expected conclusion: Arthroscopic double-beam anatomical reconstruction of the medial patellofemoral ligament is an effective minimally invasive technique.
Keywords: knee joint; medial patellofemoral ligament; double-beam anatomical reconstruction; arthroscopy
